Opinions needed on this Firebrick

Here is the spec shet from the company. Cemex has it locally in stock.
They are 2 1/4" thick x4 x9. $ 1.75 each

Specs say low duty I thought medium duty was prefered but that term can be subjective.

What do you all think?

27.6% alumina.....perfect. These will be fine. The duty rating refers to the wear, no need to spend extra $$ on medium duty. Many of us have used light duty (fireplace bricks in my case). You will have a bit of compensating to do because of the dimensions...I think we all have. Don't be concerned with the 2 1/4" thickness, mine are the same and my oven performs perfectly, although I have nothing to compare it to.

SummerJ,

These are the same bricks I used in the buff color. I have used the oven a couple dozen times and they're performing great! I don't think I would want something with higher alumina content because I believe you'll burn the bottom of the first few pizzas until it the hearth cools down. I fire my oven up until the dome clears and then spread the coals for about a 30 minutes. Then I'll move the coals/fire to the left side of the oven and mop the floor with a damp mop to remove soot/ash. Then let the hearth cool for 15 minutes and I still slightly burn the bottom of the first couple pizzas before the top completely cooks. So the first few pizzas I let the bottom get close to burning and then hold the top near the dome. The toppings cook immediately near that dome!

Those bricks should be just fine!

@Pizza Bob. Do you have a nice flame going while cooking your pizzas?

I usually keep a flame this size or slightly larger going throughout the pizza cooking. The most pizzas I have done is about 16 and I'm certain I could have kept that going. I never had to pull the coals back over the cooking area - I think it's insulated really well!
